I'm trying to display meesages in recyclerview.
Message 1
attachment-1
attachment-2
Message-2
attachement-1
Messge-3(without attachemnts)
I'm creating a new Recyclerview if row has an attachments.The click listener isn't working for the RecyclerView the listener works fine for all other view elements except RecyclerView.
MsgCursorAdapter
public class MsgCursorAdapter extends CursorRecyclerViewAdapter<RecyclerView.ViewHolder> {
private static final int VIEW_HOLDER_TYPE_1=1;

public MsgCursorAdapter(Context context,Cursor cursor,PostMessageClickListener listener){
super(context,cursor);
mcontext=context;
mCursor=cursor;
itemClickListener=listener;
}
@Override
public int getItemViewType(int position) {
if (mCursor.moveToPosition(position))
{
PostItem postItem=PostItem.fromCursor(mCursor);
if (postItem.isFromMe())
{
return VIEW_HOLDER_TYPE_1;
}
else{
return VIEW_HOLDER_TYPE_2;
}
}
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, Cursor cursor) {
PostItem postitem = PostItem.fromCursor(cursor);
switch (getItemViewType(cursor.getPosition())) {

if (attachmentArrayList.size()>0)

}
@Override
public int getItemCount() {

public static class ViewHolder extends RecyclerView.ViewHolder {
public TextView txtViewTitle;
public ImageView imgViewIcon;
public ViewHolder(View itemLayoutView) {

}
How can I create Click listener for the nested RecyclerView Items
I've tried searching SO for similar solution I didn't find any
